The Dallas estate, which boasts a 29,000-square-foot mansion, pool house, and guest house, was originally designed in 1939 for the Italian count Pio Crespi and his American wife Florence by architect Maurice Fatio.

Tom and Cinda Hicks moved in 16 years ago, and have been renovating, restoring, and expanding ever since. The Real Estalker reported that Hicks spent $100 million of his estimated $1 billion fortune renovating this stately property.

The house has 14-foot ceilings, a country club-sized pool, gardens, a movie theater, tennis court, and an undisclosed amount of bedrooms and bathrooms (though at 28,996-square-feet, we're guessing it can comfortably fit multiple sets of families if necessary).
